One day little Johnny was digging a hole in his backyard.
The next-door neighbor spotted him and decided to investigate.
“Hello Johnny, what are you up to?” he asked.
“My goldfish died and I’m gonna bury him, “Johnny replied.
“That’s a really big hole for a goldfish, isn’t it?” asked the neighbor.
“That’s because he’s inside your cat!”
